A system is the minimum function + experience. But the experience must be the focus of design from the beginning, or else, we will limit the experience to the confines of what's possible from the system, rather than creating the experience from what's possible from the world.

You must also set a limit on the features, because otherwise you will never finish developing, adding features on the fly.

Note

A guiding principle for this is keeping in mind is that human attention is limited by by time, and they can't possibly explore every possible ways in which they can use a complicated system. Although it is sometimes appealing to a user to have a tool which can do everything, when given such a tool, they sometimes choose to not make use of it, preferring to many things manually.

This is often because the tool isn't tailor-made to fit their needs. But it is also because sometimes humans need a more free access aside from their own systems.

This is the reason for the appeal towards simple systems.

Note that simple doesn't mean easy, as easy often refers to having to do no effort at all, while simple is about having finer control over the systems. Also, complex doesn't necessarily mean complicated, as a system that can be built from several parts can still be easy to work with.
